Iron(III) Oxide
Name:
Iron(III) Oxide
Alias:
Hematite; Rust; Ferric Oxide
Formula:
Fe2O3
Molar Mass:
159.6882

Fe2O3 is a reddish brown powder at room temperature. It is insoluable in water. Fe2O3 is the main ingredient of iron rust.

Example Reactions:
• Fe2O3 + 3CO = 2Fe + 3CO2
• 2Al + Fe2O3 = 2Fe + Al2O3
• Fe2(CO3)3 = Fe2O3 + 3CO2
• 7Na2O2 + 2FeCr2O4 = Fe2O3 + 4Na2CrO4 + 3Na2O
• Fe2O3 + 3H2O = 2Fe(OH)3
• 2Fe + 3H2O = Fe2O3 + 3H2
• Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O
• Fe2O3 + CO = 2FeO + CO2
• 2C + O2 + CO + Fe2O3 = 3CO2 + 2Fe
• 4H2S + Fe2O3 = 2FeS2 + 3H2O + H2
